To will whom it may concern,.-

Beit known that I, JAMES H. SWrNoELL e resident of Pittsburg, in the county of Al egheny and State of Pennsylvanie, have in- Vvented certain new and usci ul .linproveinen ts in Gos-Producers; and I do herebydcclnre the following to be n full, clear, and exact dcscription of the invention, such as will enable others skilled in the ort to which it appertans tomakennd use the seme.

invention relates to an improved gns- M prodlicer, and more particularly to a. suction gas-producer for ges-eng1nes, the object of the mven tion'bein to provide improvementsY of this character o compnet form, automatic in its control of the ges produced, and of simple and durable construction.

A furthericbiect is to provide improved stecnlenerating and automatic means for controlling its supply as well es the air-supply to the combustion-chamber.

A further objectis to provide improved construction of combustion-chamber, cooler, scrubber, end urifier, im roved watensesi pens for the es 1pit and liottom of cooler, the 'latter ermitting the removal of tsr with.-

ing the operation of the apparatus, and various other improvements in construction and operation, which will hereinafter e eer.

Wil, these and other objects in View the invention consists in certain novel features or l n view in vertical tion-chamber construction and combinations and nrrenge ments of erts, as will be more uiy hereinafter descrl ed, and pointed out in the claims. In the accompenlying drawings, Figure 1 is ongitudinal section illus-` trating my improvements. Fig. 2 is a view in side elevation. Fig. 3 is a view in front end elevation. Fig. 4 is Ya view in horizontal sectionel view, and Fig. 5 is e top plan view.

1 represents the casing of my improved appnratus, which conteins within 1t combus- 2, cooler 3, scrubber 4, and purifier 5'. The combustion-chamber 2, which is made its upper portion end rectanguler et its lower port1on,1sprovided with suitable Wells 6, of masonry, and is su lied with fuel by any approved form of bei opper 7L In the ower rectangular portion of chamber 2 an inclined grate 8 is located and adapted to direct the ashes into water-seal an 9, and a. seal-plete 10 is provided at the orward end of the fire-chamber to prevent any entrance of nir through the pen 9. A

pipe 11 connnunicates with the sriece below l the grote 8 for the admission thereto of nir l and steam, ns will be hereinafter described.

l Ges is discharged from the upper end of I chamber 2 through o neck I2 into one side of cooler 3. Seid cooler comprises upper end lower horizontal boxes l3 and 14, respectively, connected by a series of verticni tubes or pipes l5, end removable covers 16 close openings in the top of upper box I3 directly over the' tubes to crmit ready clcnning of seid tubes. These )oxes 13 and 14 are provided with partitionslT, located about one-third of the distance from opposite ends, compelling the gas to passdovsn one set of tubes 15 to box i4, thence up through nnother set of tubes to box 13, and again down through another set of tubes to box 14, from which the ges posses through n pipe 18 into the bottom of a scrubberchambcrl below e grate 19 therein, su portingy charcoal or other like material. V'1 c tubes l5 of cooler Sere surrounded by Water in seid coolerchamber, supplied by n pipe 2U 2l, directing theA Water into the bottom of seid chamber. The Water, more or less heated by the gas, escapes et the upper end through e ipe 22, discharging the seme through e. per orated coil 23 in `Sorubber-clmrnber 4 onto the coke therein, compelling the water'to poss in countercurrent to the gas and is carried ofi" throu h a tra -pipe24 at the bottom'of said cham er. ilhe cooler 3 is provided with a laterallyelongated Water-seal pan 25, which forms the bottom of box i4 and serves to catch all ter de osited by the'gas and which can be removed) from time lso-time through the lateral peratus. i

Scrubber-chernber 4 is divided from purifier-chamber 5 beside the some by a verticalpertition 2o, which. letter has en opening in lts upper portion permitting the gas to enter chamber 5 and pass down throu h suitable materiel on e grote 27 therein encbe sucked out through a pipe 28 to the engine, and suitable doors 29 are rovided for chambers 4. and 5 to permit t chambers.

Around the hottest ortion of combustion- Y chamber-2 e Water-tan 3() is located and supplied With water through pipes 20, 3l, 32, 33, 34, and 35, end spigots 36 and 37, respectivel are provided on pipes 2() and 31 for generated in tank passes through a pipe extensions of the pon et either'sxde of the epe ready access to seidV supp ying water to the pans 25 and 9. Steam IDO IlO

parts 38, past a throttle-valve 3) therein, through a pipe 4l.) 4l to draft-pipe l1, and said draftpipe 1l has an upright extension at one end, provided with a damper 42 in its u )per end, the operation of said damper 42 and valve 30 being automatically controlled, as will now be explained. y

The supply of air and steam to draft-pipe l1 is governed by the suction of the engine, the suction controlling the movement of a diaphragm in chamber 43, connected by a pipe 44 with suctionpipe 28. Connected wlth the diaphragm is a rod 45, pivotally connected at its other end with a walkingbeam 46,one end of which is connected b a rod 47 with throttle-valve 39 and the ot er by a rod 48 with damper 42. As the suction of the en e increases rod 45 will be moved to the rig t, causing the walking-beam 46 tol close steam-valve 39 and open aindamper 421, increasin the supply `of air to the fire and causing t e same to grow hotter and produce more gas. As the suction of the engine decreases rod 45 will be moved to the left, closing damper 42 and opening steam-valve 39 increasingthe supply of steam under the grate of the combustion-chamber and causing the tire to diminish, and it will be observed that this mechanism at all times controls the proportion of air and steam to draft-pipe 11, and thereb regulates he intensity of the fire to suit t e operation of the engine, and while I illustrate a dia )hragmchamber as the automatic means do. not wish to be restricted to this specific device.

A. great many slight changes might be made in the general form and arrangement of described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself atliberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
